Specificity of P-Lhcb1 and P-Lhcb2 antibodies.

Arabidopsis wild-type (wt), stn7 (SALK_073254) and psal (SALK_010554), stn8 (SALK_060869), stn7stn8 plants were subjected to state 1 and state 2 light conditions, and then proteins were extracted and immunoblotted with antibodies specific against phosphorylated and non-phosphorylated Lhcb1 and Lhcb2 forms.

(a) Immunoblots. The specificity of antibodies is indicated on the left side.

(b) Densitometric analysis of immunoblots. Intensity of signals has been normalized respect to the value in wild-type state 2.

(c) Difference in phosphorylation between state 1 and state 2.
